In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models , which need separate voltages to power the motor and the RC equipment.
November 1925 magazine ad for battery eliminator. A battery eliminator is an adapter intended to allow a device intended for battery operation, such as a radio, to be operated from an AC outlet. [10] All radios, except crystal sets, used inconvenient and messy vacuum tube batteries until the mid- to late-1920s. Battery eliminators that plugged ...
The type of battery and number of cells connected is an important consideration when choosing a battery eliminator circuit (BEC), whether built into the controller or as a stand-alone unit. A higher number of cells connected will result in a reduced power rating and therefore a lower number of servos supported by an integrated BEC, if it uses a ...
Philco (an acronym for Philadelphia Battery Company) [1] is an American electronics manufacturer headquartered in Philadelphia. Philco was a pioneer in battery, radio, and television production. In 1961, the company was purchased by Ford and, from 1966, renamed "Philco-Ford". Ford sold the company to GTE in 1974, and it was purchased by Philips ...
RC servos are usually powered by the receiver, which in turn is powered by battery packs or an electronic speed controller (ESC) with an integrated or a separate battery eliminator circuit (BEC). Common battery packs are either NiCd, NiMH or lithium-ion polymer battery (LiPo) type. Voltage ratings vary, but most receivers are operated at 5 V or ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A batteryless radio is a type of radio receiver that does not require the use of a battery to provide it with electrical power. Originally this referred to units which could be used directly by AC mains supply (mains radio); it can also refer to units which do not require a power source at all, except for the power that they receive from an ...
The JST RCY-series connector is a 2.5mm-pitch and manufactured by J.S.T. Mfg. Co., Ltd. [8] It is known in radio control circles as the battery eliminator circuit (BEC) or P connector. JST also produces other types of connectors that are used in R/C and hobby electronics.
